Hello CodeForces Community. There's no doubt about the importance of having a good problems' analysis after programming contests. I am disappointed about the Rounds Tutorials (and I think many others are) because of the following reasons :
They don't necessarily exist for some recent contests :-/
If they existed , then in many cases I encountered the following situations :
Written partially or totally in Russian.
Written in ambiguous English.
Written "unofficially" , i.e some user who participated in the contest decided to share his ideas. This might be inconvenient because the methods he used can be different from the intended solutions which are generally more elegant.
Not complete. Solutions for some problems are missing with a promise of adding it "soon". This "soon" often turns into "never".
- If none of the previous problems occurred , then sometimes I feel that the tutorial is disappointing because it's not discussing any of the problems in enough depth. The writer merely sketches a few hints that aren't enough for someone seeking a full solution.
Please note that this isn't "another annoying complaint" about the website. I think CF is one of the best competitive programming platforms ever created , and I enjoy participating. While I think it does take a lot of effort in organizing a CF contest ( from creating the problems themselves , through testing and checking the problems' statements .. etc) , I think it should be somehow "obligatory" to have an "official" tutorial after each CF round. Take Round #174 by scott_wu (and others) as an example. It was wonderful to have an excellent tutorial just after the end of the round. I think if this is done , then it'd be a big plus for the awesome CodeForces website.
